OBJECTIVE Decompressive craniectomy (DC) is a life-saving treatment for severe hemorrhagic cerebral venous thrombosis (CVT). However, the correlations between the clinicoradiological features and surgical outcomes of this disease are not well established. Therefore, the authors endeavored to analyze the potential risk factors for this more severe subtype of CVT and to provide more evidence regarding the benefits of DC in patients with hemorrhagic CVT. METHODS The clinical features, radiological findings, and surgical outcomes of patients with severe hemorrhagic CVT who had undergone DC treatment in the period from January 2005 to March 2015 were retrospectively analyzed, and the risk factors for this disease were evaluated...

Cerebral cavernous malformation is a neurovascular abnormality that can cause seizures, focal neurological deficits and intracerebral hemorrhage. Familial forms of this condition are characterized by de novo formation of multiple lesions and are autosomal-dominantly inherited via CCM1/KRIT1, CCM2/MGC4607 and CCM3/PDCD10 mutations. We identified three truncating mutations in KRIT1 from three Japanese families with CCMs: a novel frameshift mutation, a known frameshift mutation and a known splice-site mutation that had not been previously analyzed for aberrant splicing...

INTRODUCTION: The level of residual cognitive function in patients with early brain injury is a key factor limiting rehabilitation and the quality of life. Although understanding residual function is necessary for appropriate rehabilitation, the extent of its effects on cognitive improvement remains unknown. The present study evaluated cognitive function in patients with severe motor and intellectual disabilities after early brain injuries due to cerebral hemorrhage (CH) or periventricular leukomalacia (PVL)...

Cerebral air embolism is a recognized life-threatening complication, sometimes iatrogenic. Its timely diagnosis is essential because it can result in neurologic deficits or death. We report a case of a 58-year-old man who died from cerebral air embolism diagnosed by nonenhanced computed tomography scan of the head after a cardiac bypass surgery with Biventricular Assist Device and multiple vascular line placements. Autopsy revealed extensive subcutaneous emphysema, intravascular and perivascular air bubbles in the central nervous system and associated cerebral and cerebellar hemorrhagic infarction...

BACKGROUND: In subarachnoid hemorrhage (SAH), occurrence of cerebral vasospasm (CVS) mediated by endothelin (ET)-1 might be a result of a compartmental inflammatory response with interleukin (IL)-6 release. We aim to investigate the relationship between ET-1 and IL-6 in association of CVS. METHODS: A total of 24 New Zealand white rabbits where randomly allocated into 3 groups: SAH (n=10), IL-6 (n=10), and sham (n=4). SAH was induced by a closed cranium extracranial-intracranial shunt model...

Post-radiation leukoencephalopathy is characterized by cognitive impairment and white matter alternations on imaging. Cerebral small vessel disease (SVD) is one of several suggested etiologies. Cerebral microinfarction (CMI) is a recently described marker of SVD. We sought to examine the rate of CMI as a biomarker of ongoing ischemia among patients who underwent brain radiotherapy (RT). 110 patients treated with RT for primary or metastatic brain tumors were enrolled. A total of 685 brain MRI tests performed 1-108 months post-radiation were examined...

Stroke is known to frequently recur in patients with a history of cerebrovascular disease, and the control of hypertension is extremely important for the treatment of those patients. The robust relationship between the recurrent cerebrovascular disease and blood pressure control has been demonstrated in large-scale clinical studies. The antihypertensive drug therapy significantly reduces the recurrence rate of all types of cerebrovascular disease, incidences of myocardial infarction and all vascular events...
